History

Construction of the Yanfang Line was scheduled to commence in September 2011 and be completed by 2013.[3] On October 17, 2011, the Ministry of Environmental Protection declined to approve plans for the line citing lack of approval for the project from the National Development and Reform Commission and uncertain environmental impact of the line on the South–North Water Transfer Project which has a channel and reservoir in Fangshan District.[4][5] As a result, the onset of construction was delayed to at least the end of 2013.[5]

Construction on Yanfang Line was started in April 2014. The line is scheduled to open in 2017.[6] The line opened on December 30, 2017.

Technology

The line is the first in Beijing to be capable of unattended train operations, and the first in China to exclusively use subsystems developed by domestic manufacturers.[8]

Future Development

The 6.1 km (3.8 mi) branch line of Yanfang line, from Raolefu station to Zhoukoudian Town station is under planning. Due to low passenger flow, the branch line will not be built in the short-term planning.[9]
